You don't sound argumentative at all, Jasp!
I do understand what you are saying, but for now of course he is only going to say what has been told by the killer, CD.
Every DA in this country is at their happiest when any defendant/s confesses. It locks CD in to his 'story.' He cant go back and retract it now and in so many areas it is glaringly obvious he is lying.
Imo, if this goes to trial his confession will be shredded by the Prosecutor and will not be backed upped by the evidence once its all in. IMO
I find Kratz' statements much more plausible to believe. In fact before this goes to trial I wouldn't be surprised if the DA cuts a deal with Kratz in the future for less time served or takes the DP off the table if he testifies against the mastermind (CD) who admitted he shot all four victims.
It wouldn't be the first time a named co-conspirator testified against the main perpetrator and was given a plea deal.
